Madame Victoria Karnstein shares her surname with the sisters in the Hammer horror film Twins of Evil 1971.
The Caretaker is set during 1973, an important time as The Exorcist 1973 was released and banned in South Africa due to its Catholic routes in the Apartheid regime.
When Alanna Krynau arrives at the house, it parallels to the same shot and lighting of The Exorcist Featuring Max Von Sydow and Ellen Burstyn.
The signature short bows of The Caretakers theme were the first key motifs that made the director/composer write the story. It started with Alanna walking to the manor of the Karnstein residence.
There are two Camille Saint Seins songs in the directors cut of The Caretaker. Danse Macabre and The Carnival of Animals.
